ther object of my invention is to provide an improvedhydraulic drill feeding mechanism 'and more particularly a. feeding mechanism of thecharacter mentioned in which it is made'possible to obtain a long feed without increasin the length of the feeding mechanism and while enabling the latter to be'maintained relatively compact longitudinallyei s In the -accompanying. drawings I have shown for purposes of illustration one form which my invention'may assume in .practice. I

Inthe drawings,- F'g. 1 is a front elevation of a drilling apparatus constructed in accordance with my improvement. v 4 a Fig. 2 is .a side elevation of the same in vertlcal section. y

In this illustrative construction I have shown an apparatus of the general type describedand claimed in'm copending application Ser..'No. 619,835, led Feb. 19', 1923, the same comprising a suitablemotor or engine -1 operativel connected to a' reel '2 and to a rotating tu ular member 3 of olygonal cross'section for a rod line a apted to extend through said member 3 and be ro and to be fed by hydraulic tated' thereb feeding ,mec anism includin'ga hydraulic cylinder 4, the hydraulic feeding'mecha- 'nism being improved as, hereinafter described, together with someiof the connections to-therotating mechanism and the support on which the whole mechanism is carried and withwhich it is movable bodily relative to the hole and the machine base.

sleeve 10 suitably attached thereto at the u bottom o f-the cylinder and herein extendmg therein up through the cylinder into the-removable top head of the c linder. Moreover, the. piston .11 in the cy inder 4 carries .a sleeve 12 of greater diameter than no the sleeve 10 and fitting closely around the same. This sleeve 12 is connected at its upper end in-a usual manner to the swivel head The swivel head 13 specifically colnprlses upper and lower ball thrustbear- 66 ings llf and 12, respectively, between which a collar 13 is inter osed, the collar being threadedlyronnecte to the upper end of the rotating member 3 which carries the rod ,line. The sleeve or piston rod 12 is se--70 cured as by screws to the lower part of the swivel head casing. It will'thus be evident that the piston 11 is operative to feed the sleeve 12, the swivel head 13, 'and'the ro-Q tatingmember 3, b which the 'drill rods are carried, upwar 1y or'downwardly as I desired, the thrust of the rod line bein absorbed by the thrust bearings 11 an 12 within the swivel head 13, allas well known 'in the art. The sleeve 12 is also packed at the top of the; cylinder by .a suitablepacking 14 held in position on the vtop of the cylinder through holding means comprising a removable clamping sleeve and screws 15. Asshown, the lower end of the sleeve 12 is 86 flan ed and rests on a flange 16 in the bore of t e pistonand is'clamped thereon by a ring and screws 17. 'A packing 18 is also inserted between the lower end of the sleeve 12 and the outer periphery of the sleeve 10 90 telescopically-carried thereby, this packing 18 being held in place by a'clampingmeans including a ring and screws '19.

In the operation of my im roved construction it will of course be un erstood that 5 when fluidis supplied to the opposite sides ofthe piston in the general manner comscope in such manner as to enable the dc sired' operation while giving a very com-. pact construction longitudinally and avoidmg any ob'ectionable leaking between the .105 opposite si es of the piston. As a result of my improved construction, it will be oblerved that it is made possible to use a over, it will be noted that by changing the connections between the. gears 7 and 8 a' still'further reduction in necessary height below the gear 7 is made possible. These and other advantages of my improved construction will, however, be clearly apparent to those skilled in the art.

While I have in this application spe cifically described one form which my in vention may assume in practice, it willbe understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without de-.

parting from its spirit or the scope of the appended claims.
